TUNING-PEG FOR VlOLlNS.

SPECIFICATION forming part of Letters Patent No. 444,972, dated January 20, 1891. Application filed March 31, 1890. Serial No. 345,976. (No model.)

To Cb whom it may concern:

Be it known that I. RUDOLPH O. BooKsnn, a citizen of the United States, residing at Buftale, in the county of Erie and State of New York, have invented new and useful Improvements in Tuning-Pegs for Violins, &c., of which the following is a specification.

This invention relates to the tuning-pegs of violins and other stringed instruments.

The object of my invention is to provide a tuning-peg to which a string may be quickly and convenientlyattached with as little delay as possible, and to provide the peg with a simple and effective clamping device whereby slipping of the peg in its opening is prevented.

In the accompanying drawings, Figure 1 is an elevation, partly in section, of the head of a violin provided with my improved tuningpeg, three of the pegs being shown in elevation and another in section. Fig. 2 is a side elevation of the head. Fig. 3 is a cross-section of the peg. Fig. at is an elevation of one of the metallic washers. Fig. 5 is a sectional elevation showing a modified construction of the peg.

Like letters of reference refer to like parts in the several figures.

A represents the head of a violin, having the usual holes for receiving the tapering tuning-pegs B. Each peg is provided near its large or headed end with ametallic collar or washer c, surrounding the peg and bearing against the adjacent outer side of the head A. This collar is preferably formed within its opening with inwardly-projecting spurs (Z, which embed themselves in the wooden body of the peg and prevent slipping of the collar on the peg. I

e is a clamping-nut applied to the opposite small end of the peg and bearing against the adjacent face of the head.

XVhen the peg is constructed of ebony or other hard wood, a screw-thread may be out directly on the wooden peg, as represented in the drawings; but when the peg is made of softer wood an externally-threaded cap or sleeve is secured to the end of the peg. Washers ff, of rawhide or other suitable frictional material, are preferably interposed between the sides of the head and the collar 0 and nut c to increase the frictional contact between these parts. Upon tightening the clampingnut c the latter and the collar 0 are caused to firmly bear against opposite sides of the head, thereby clamping the peg in the head sufficiently to prevent accidental slipping thereof, while at the same time permitting it to be turned.

It is obvious that my improved clamping device is equally desirable for the tuningpegs of guitars and other stringed instruments.

f represents alongitudinal socket or opening ext-ending inwardly from the small end of the peg into the body thereof, and g is a transverse slot or recess formed about centrally in the peg and intersecting the longitudinal opening f between the ends thereof.

h is a movable pin or rod seated in the longitudinal opening f, and to which the string is attached by looping the string around the portion of the pin exposed through the transverse recess 9.

The string is readily attached to the peg by drawing the pin it outwardly a sufficient distance to clear the transverse recess, forming a bend or loop in the string and placing it into the recess and then pushing the pin back into place, so as to pass through the loop of the string. The bent or doubled portions of the string are crossed in the usual manner to prevent slipping of the string upon turning the peg to tighten the string.

The operation of attaching the string to the peg is performed very rapidly and with greater convenience than by the usual method of passing the end of the string through a diametrical opening in the peg.

My improved fastening is especially desir ablein the event ofa stringbrealzing in ensemble playing, where all the string instruments are indispensable, as it enables a new string to be readily strung up by simply forming a loop in the string at the proper point without requiring its end to be passed through the peg and a considerable portion of the string drawn through the opening in the peg, which involves unnecessary delay.

In the modified construction represented in Fig. 5, a spiral springt' is employed, which tends to hold the pin in place in the peg. The outer portion of the pin is reduced to form a shoulder 77, against which the inner end of the spring bears. The opposite end of the spring is secured Within the cavity of the peg by driving its end into the Wood, as shown.

I claim as my invention 1. A tuning-peg for stringed instruments, provided on one side with a transverse recess, a longitudinal socket or opening extending from the end of the peg inwardly beyond the transverse recess and intersecting the same, and a movable pin or rod seated in said 10ngitudinal opening, around which the string is looped, substantially as set forth. a

2. A tuning-peg for stringed instruments,

provided with a longitudinal socket or opening extending inwardly from the end of the peg,a transverse recess intersecting saidlongitudinal opening, a movable .rod or pin inserted in said longitudinal opening, and a spring whereby the pin is held in its opening, substantially as set forth.

WVitness my hand this 28th day of March, 1800.

RUDOLPH o. BOOKSER.
